Cutting propagation method of purple leaf plum

[Agricultural Products Network] Purple leaf plum is also called red leaf plum. She is eye-catching with purple shiny leaves. In the green leaves, like a plant that is unbeaten, it forms a beautiful landscape in the green mountains and green waters.

What we are going to introduce here is the breeding method of purple leaf plum.

[Reproduction method of purple leaf plum] Insert preparation: Select a tree that is 3 to 4 years old and grow robust as a mother tree. After the autumn leaves are cut off from the mother tree, the current branches without disease and insect pests can also be used as cuttings in combination with plastic trimming to cut the thick and buds, full of pests and diseases and mechanical damage. Cut the selected cuttings into 40 to 50 cm branches, bundle them from 100 to 200, and store them in wet sand.

[Proliferation method of purple leaf plum] Selection and land preparation of nursery: The nursery should choose the place where irrigation and transportation are convenient, and the soil layer is required to be deep, fertile and loose sandy loam. Before the preparation of the ground, spread 1 to 1.5 tons of decomposed farmyard manure per mu, and sprinkle it with 50% carbendazim 1500 g or potassium permanganate in the soil for soil sterilization; then use 4000 g of 50% zinc sulfur. Phosphorus granules are applied to kill underground pests. Then deep ploughing, fine hoeing, leveling the land, removing debris such as weeds and agricultural film, and doing cockroaches. According to the depression, the length of the raft is 1 meter wide; the ditch between the raft and the raft is 0.3 m wide and 0.2 m deep. After doing a good job of repression, the hoe will be ploughed and prepared for cutting.

[Reproduction method of purple leaf plum] Cutting time: from late November to mid-December.

[Reproduction method of purple leaf plum] Cutting method: Before cutting, first cut the branches that have just been cut or stored in the wet sand, cut off the weak branches and the water shrinking and shrinking parts, then cut the long branches from the bottom up. Growing 10 to 12 cm, with 3 to 5 buds of cuttings. The near bud at the lower end of the cuttings is cut into smooth slopes to increase the contact surface between the formation layer and the soil, which is conducive to rooting. The upper end of the cuttings is cut into a plane at a distance of 0.8 to 1 cm from the bud. After cutting the cuttings, immediately immerse the lower end of the slope in water for 15 to 20 hours to allow the cuttings to fully absorb the water. The rooting agent was prepared by using 50×10-6ABT6 rooting powder in proportion, and the cuttings were immersed in the roots to facilitate rooting. The cuttings are inserted obliquely downward into the soil, with a row spacing of 5 × 5 cm, and the upper buds are exposed to the ground by 0.5 to 1 cm. Immediately after the cutting, the water is drained and the cuttings are intimately connected with the soil. After the ground is slightly dry, cover the sputum with a double-layer mulch, and at the same time, put a plastic small arch shed with a width of 1 meter and the same width on the surface to protect the heat and keep warm.

[Reproduction method of purple leaf plum] Management of cutting seedlings: The seedbed and the small arch shed can be kept for a long time without watering, such as the soil under the mulch is dry, and then the water is irrigated along the gully. When the minimum temperature drops to minus 5 °C, the straw curtain should be added with anti-freeze insulation; when the minimum temperature rises to 0 °C, the curtain will be uncovered during the day, and the grass will be surrounded by the night; when the minimum temperature reaches 5 °C, the arch shed should be opened during the daytime. Properly release the wind and prevent high temperature from burning the seedlings. At the beginning of March, when the seedlings were 3 to 5 cm high, the film was ventilated during the day, and the ventilation was gradually increased with the growth of the seedlings. From mid-late March to early April, pay attention to keeping the seedbed moist. The shed film was removed in mid-April and fertilized, weeded and watered in time.

[Proliferation method of purple leaf plum] Transplant seedling management: In late April, transplanted after 4 pm on cloudy or sunny days. Before the seedlings, the seedbed is filled with water to facilitate the reduction of the roots and the roots can bring more soil. Seedlings are now planted to improve the survival rate of transplants. The row spacing of the plants was 20 cm × 30 cm. Before transplanting, apply 4 to 5 tons of decomposed farmyard manure and 0.05% of ternary compound fertilizer with 15% of each compound, and transplant after deep cultivation. After planting, the water is poured, the seedlings are kept dry but not wet, and the pests and diseases are strengthened. At the beginning of June, before the rainy days or before the soil was dry and irrigated, 0.025 tons of urea was applied per mu to promote the growth of seedlings. In the same year, the average height of transplanted seedlings was about 1.5 meters and the ground diameter was 1.5 cm.

The above is the basic breeding method of purple leaf plum.
